BOOKBINDING-MACHINE.

Specification of Letters Patent.

Patented Aug 27, 1912.

Application filed December l5, 1908. Serial No. 467,623.

To all whom it may concern:

Be it known that I, DANIEL E. vVoom-runn, a citizen of the United States, residing in} the borough of Manhattan, city, county, and; State of New York, have invented certain; new and useful Improvements in Bookbind ing-Machines, of which the following is a: specification, reference being had therein toi he accompanying drawings, which form a;

p art thereof.

My invention relates to book binding machines, and more particularly to a type thereof adapted to folda reinforcing strip of tape, cloth or paper, if desired, upon a.

pamphlet.

The machine of my invention has application more particularly to the binding of coupon bonds and other similar pamphlets,

wherein the binding is for the purpose mainly, of giving a neat finish to the bond; rather than to act as a hinge. This binding, is for both sides of one edge of the bond,; and customarily, the various sheets consti-- tuting the bond are previously united by staples. Heretofore the binding or backing strips have been applied by hand, and this work required a high degree of skill to avoid the soiling or mutilation of the bonds,

quently results'in great confusion.

be main object of my invention is to apply a backing or binding stripto a coupon, bond by mechanical means which will fold a. strip of material across the hinge or back: of the bond and upon both sides thereof, thus supplanting the old hand methods, and not only insuring increased capacity, but; uniformity and precision in the work itself.

A further object is to provide a machine of this character embodying a strip feeding and folding mechanism, a glue pot, for making the same adhesive, a bond feedingmechanism, and a presser mechanism for applying the adhesive strip to the bond after it has been folded thereon by the feeding and fold ing in echanism.

A still further object is to provide a ma:

chine of this character which will apply a continuous strip of cloth or paper to bonds in rapid succession, and thus permit a high efficiency in the machine, while running at a comparatively low rate of speed.

A still further object is to provide a machine adapted to apply a continuous strip to successive bonds, wherein the bonds will be so spaced apart, as to afford ample room for the separation and trimming thereof without likelihood of mutilation.

A still further object is to provide a machine of this character wherein a continuous strip is applied to a succession of bonds and said strip is automaticallysevered into lengths approximating the length of the binding, after being attached to the bonds.

A still further object is to provide a machine of this character, in conjunction with a strip feeding and pasting mechanism, means whereby a continuous strip will be scored while passing through the machine, so as to facilitate thefolding operation and insure precision in such operation.

A still further object is to provide in a machine of this character, a synchronized intermittent movement of the strip feeding and folding mechanism, the pamphlet feeding mechanism, and the shears, whereby the application of the binder will be by a continuous operation, and the succession of bonds, enchainedby the binder strip, may be separated one at atime and discharged separately into the collecting mechanism of the machine. 7

A still further object is toprovide a feeding mechanism which will feed the coupon bonds, in a perfectly flat position so as to prevent the displacement of the sheets, or the creasing or wrinkling thereof.

A still further object is to simplify the structure of the machine by utilizing a feeding roll for pressing the strip upon the bond, and feeding the strip forward to position it properly for the next bond.

A still further object is to provide a folding mechanism wherein the strip will be gradually folded so as to pass over both sides of the bond at the hinge thereof, with the adhesive surfaces presented inwardly, and the said surfaces held separated so as to prevent their adhering together before the bond has been inserted therebetween.

A still further object is to provide various adjustments for the feeding mechanism,

and the shears, whereby bonds of different widths may be bound in a machine.

A still further object is to provide a-suitable adjustment for the presser roll to permit its regulation to insure the proper application of the strip to the bond. And a still further object is to provide a machine of this character which will be simple in de-' sign, and in its mode of operation, and inexpensive to produce.

The invention consists in the'novel features of construction and combination of a plan view of a machine embodying my in. vention, having three bonds thereon shown. ,partly'in full lines and partly in dotted' lines, the feeding shelf and the collecting shelf being partly broken away Fig. 2 1s a side elevation of the machineshown in Fig.

The sprockets c c areso spaced apart In the embodiment of my inventiomi shown in the drawings, the frame A o'fthei machine is shown as supporting a sectional table cousistingof three parts, B, B, B so spaced apart as to leave ways or channels (3,, G, between said sections for the carrying} chains of the feeding mechanism. Atone end scoring and tensioning mechanisms 7 the several views.

of the sectional table is a feeding'shelf D,

having a bevel leading to the machine top, and at the other end thereof is a collecting:

shelf E, having a retaining flange E:

Alined with the part B is a guide flange F,

which serves as a guide for the bonds as they pass through the machine.

' 'The main driving inechanism consists of "a pulley Gr driven from a motor H or any other desired source of power.

In the further description-of the machine,

forthe purpose of greater perspicuity, the

various mechanisms will be considered separately, and described with relation to the succeeding operations on any bond, although all of these operations are carried on simulf taneously, each performing its function, at the same time, butupon HndlfiCIGIlt ob ect,

or a different part ofone object. A logical division of the machine along these lines would therefore consist of'the bond feeding mechanism; the strip pasting and guiding mechanism; the strip folding mechanism; the strip presser mechanism, which would include the mechanism employed for holding the bond in the proper position while the binding is being applied thereto; and the shear mechanism, the feeding and collecting shelves, requiring no detailed description beyond that above given. Before entering into this detailed description, it is necessary to point out that through the necessity for synchronizing the actuation of the various mechanisms, it is desirable to have them all actuated from the same main shaft, and to secure that slight interval of rest necessary or desirable to permit the separation of each bond after it has been bound, and to have all of these movements intermittent. With this aim in view, I prcvide a ratchet wheel a carrying a gear a, and a lever (2 carrying a pawl a oscillating about the axis of said ratchet a. The pawl 11 is necessarily spring-pressed. Geared to the pulley G, by the entrained gears G is a gear Wheel G and pivotally' connected eccentrically of the gear Gr and adjustably chains belowithe top. level of the machine as to cause said chains to run in the channels C C provided in the top for this purpose. The chains, as shown clearly in Fig. 1, pass under the feedmg shelf D'so that a bond fed from said shelf will be delivered upon theunachine' top above said chains. These chains being positioned below the surface of the machine-top, the actual feeding movement is accomplished by meansof proectlons spaced apart upon the said chains,

'a distance sufiicient to accommodate the bonds between the succeeding projections, which pro ections extend'above the said top surfaces. Preferably these clips are made of spring metal, as shown in Fig. 5, and are adapted to be sprung over and engage a pivot in the-chain links. The'clips on the opposite chains 0 0*, it is needless to say, must'be placed directly opposite each other, so as to afford contacting surfaces on the samestraight-line at right angles'tothe direction of movement of the chains, and thus insure a parallel feeding movement of the bonds. In order to insure high capacity, the succeeding clips should be arranged as near together as possible, leaving suflicient clearance between the succeeding bonds, to

permit a field for the actuation of the. shears. It is desirable to provide such an adjustment of the distance between the clips as will accommodate the machine to slight variances in the widths of different bonds, such as would not materially aflect the predetermined feeding movements of the pawl and ratchet mechanism. This adjustment would, however, permit the variation of this feeding movement by the adjustment of the connecting rod Z) in a manner to be hereinafter described. To accomplish this result, the clip d is provided with one vertical edge 65, and a stepped edge (P, which step would bring the contacting point substantially midway between the pivots of any link. It will thus be observed that the distance between two clips may be shortened by simply turning the clip'around, or it may be lengthened to an extent equaling the length of a link by attaching the clip to the succeeding pivot pin, or of a half of a link by attaching it to said pin and turning it with the "straight edge (Z presented in the direction of the feeding movement.

If the adjustment is sufficiently great to necessitate a variance in the'feed, such. may be accomplished by releasing the end of the connecting rod 12 on the oscillating lever ('5 and raising it to a point nearer to, or farther away from, the axis of oscillation of said lever.

In mesh with the gear a is a pinion 6 carrying a gear 6 and a sprocket e Extending from the sprocket 6 about a sprocket 0 carried by the shaft 0 is a sprocket chain c by means of which the chains 0* receive a unidirectional, intermittent or step-by-step feeding movement.

Mounted on the frame of the machine, is a reel I adapted to carry a roll J of strip binding cloth or paper; and disposed between said reel and the folder mechanism is a mechanism K for creasing and tensioning the strip, and a glue pot L for applying glue thereto. The said glue pot has mounted therein a pasting roller f having mounted on opposite sides thereof in the direction of traverse of the strip, guiding and tensioning rollers f, F. The glue pot is heated in any desired manner as by the burner L. The tensioning and creasing mechanism. K comprises a metallic roller. 9 having a central rib g thereon adapted to fit into the circumferential recess in the roller 9 the roller 9 being flanged to guide the strip in passing through this mechanism. Disposed between the roller and the reel, is a flanged guiding and tensioning roller P. The roller g is mounted in movable bearings g and a suitable adjustment screw g is provided for the purpose of regulating the pressure exerted upon the cloth or paper binder strip while passing through this mechanism. The entire creasing mechanism is positioned between the glue pot andthe reel and serves as a tensioning device to prevent the overrunning of the reel as well as to avoid the presence of slack bet-ween the glue pot and the folder mechanism. To minimize likelihood of the lapping of the strip between the guide and tension roller 9 and the creasing rollers 9 I provide a cover 9, for said rollers which holds the strip flat while it is passing through this mechanism. After the strip leaves the glue pot, with the glued surface presented downwardly, for the twofold purpose of preventing dust and dirt settling thereon and the contact of the adhesive surface with the machine parts, it extends par allel with the chain o and passes around the guide roller h, and thence laterally away from said chains to a guide roller h, the axis of which is so pitched as to direct the strip toward the folder mechanism and permit it to be turned or twisted in the manner shown in Figs. 1 and 2 of the drawings. The rollers 72. 71 are idlers, and act merely as guides for the strip. The guide flange F has an opening therein through which the strip J passes to the folder mechanism which will now be described. 7

The folder which is shown in detail, in Fig. 3, comprises a plate z having side flanges a" 2' which at their forward ends (with reference to the initiation of the fold ing movements) are spaced apart the width of the strip and gradually converge toward their other end, so as to gradually fold the sides of the strip toward each other. One side of the folder is open to permit the bond to pass between said flanges and be inserted between the folded sides of the strip. Under some conditions, the bond might spring upwardly and engage the top fold of the strip prematurely, or said strip might collapse and thus be improperly applied to the bend, and, while the folder heretofore described will operate successfully, I prefer to provide a separator 7' attached to the upper flange 2' by means of the clip 7" which acts as an upper guide surface for the bond passing through the folder and at the same time prevents the top fold of the web from engaging same, until it has been properly folded over by the converging flanges i 2' toward the discharge end thereof. The use of the clip permits the separator j to be detached from the machine when the conditions are such as not to require it to insure correct work.

The presser mechanism consists of two members. one for applying the strip to the bond. after it has been positioned, or laid, by the folder, and the other for pressing the various leaves of the bond together and holding them against lateral displacement, while the binding strip is being placed. thereon or pressed to place. The first of these members above referred to consists of a roller 7c having an elastic surface, as soft rubber, mounted above an idler is, also having a soft rubber surface, mounted on the frame of the machine. These rollers is Z? are op posite the folder 2' so that as the bond or other pamphlet passes from said folder with the binding strip laid thereon, the bound end of the bond will pass between said rollers and :be pressed firmly therebetween. roller k is mounted on a shaft carried in an The adjustable housing 70 which shaft is rotated by means of a gear k in mesh with the gear 6. The adjustment screwslc are for the purpose of regulating the pressure exerted by the roller, is. proper regard for the diameter of the roller '70 gives a peripheral travel to said roller equalingthe lineal traverse of the feeding same diameter as, and entrained with, the 7 gear 10 by the idler gear Z Mounted on the mechanism and thus prevents the-buckling or wrinkling of the bonds by reason of any checking of the feeding movement at this point.

secondary feature of insuring a uniform feed of the bound end of a bond.

Mounted above the machine top is a shaft Z passing over the folder plate 71 intermediate its ends,"which shaft has a gear Z of the shaft Z at widely divergent points, so as to exert such a pressure on the bonds along the same straight line, as to prevent any twisting thereof during the application of the binding strip thereto and the subsequent operation of the presser mechanism thereon,

km and the said chains 0 are rollers m of elastic material or provided with an elastic cover, and of thesame diameter as the presser roller is. Mounted in the top part of B and B respectively, beneath these rollers m, are anti-friction rollers m between which and the rollers m the bonds are gripped. The shaft Z is driven at the same speed as the shaft carrying the roller 70, and consequently the rollers bond being fed by the chains 0 VAdjustably mounted on the top vB is a frame n carrying a fixed shear blade n upon the plane of the machine top and a re movable blade n positioned upon an arm n The guide flange F does not extend beyond the folder 2", thus leaving clearance for the presser mechanism and the shear mechanism heretofore described.

"Mounted beneath the machine top is an oscillating shaft 0 having slidably and adjustably mounted thereon, an arm 0 con- This construction with lVhile primarily, a power driven rotary presser is for this purpose, it has the.

nected by a link 0 with .an arm 11, the shears being actuated through theseflnienr bers. Adjacent to the other end of the shaft 7 0 is an arm 0 pivotally connected to a "slide 7 79 mounted on the frame of the machine which slide has vertical movement and is" on the shaft of the said gear G Acting V on the shaft 0 is a spring 7- tending to normally open the shears, the cam qitensiomng the sald sprlng when the shears arejactuated.

It will be observed by reference to Fig. "7,1 i

that the-cam Q is so-setas to actuate the shears while the pawl "a? is being reset preparatory to the 7 next feeding movement of the various elements of the bin'der, thus causing the shears to separate the succeeding bonds by severing the continuous strip between same, during this interval of rest. It will be observed that the varlous ,mechanisms all being actuated through the rotation of the'gear G their movement will be accurately timed, and the likelihood of damage or a disarrangenient of parts willbe reduced to a minimum,

I have indicated the bonds passing through the machine by the letter M, the various leaves thereof being secured near one, end by staples, or other securing means;

The operation of the herein described machine is substantially as follows :The bonds M are stacked upon the feeding shelf D and fed therefrom to the machine top B, B, and B with the bound edge against the guide flange F. As fed, the bonds are positioned between succeeding clips (Z and as the machine is intermittently operated, the

bond may be properly positioned during the interval of rest, which, however, is slight. Assuming that any bond is being fed through the machine, the operation would 7 continue as follows :The gear G having passed the center, oscillates the lever a through the connecting rod 6 and with the pawl a? would turn the ratchet a and the gear a carried on its shaft so as to impart a simultaneous forward feeding movement to the sprocket chains 0* through the pinion e, the sprocket 6 the sprocketchain 6 the shafts c 0 and the sprocket wheelsc '0 As the said chains advance, the clips (I thereon engage the bond'adjacent to opposite edges thereof and slide said bond along the machine top toward the folder mecha- Before starting the machine, the strip is drawn from the roll J on the reel I, threaded through the creasing and tensioning mechanism K; under. the roller f; over the gluing roller 7; under the roller ,2; through the folder'i and under the feeding and presser roller k. Hence, as the machine operates, the binding strip is fed forward at the same speed as the bond itself, the gearing actuating the roller is as heretofore described, imparting to said roller a peripheral travel equaling said feeding movement of said chains cflct While the binding strip, in passing through the glue pot and up to the roller h, is extended on a plane parallel to the top of the machine, it is turned after it leaves the roller h and passes to the folder 2' at right angles to the said top. As it passes through said folder the opposite edges thereof are gradually turned toward each other, the crease centrally of said strip insuring the fold coming centrally of said strip. The crease is shown clearly in Fig. 3, as well as the folding action of the part The converged flanges z" i gradually bring the turned sides of the strip closer together so that at the point where the strip leaves said folder, they are so close together as to actually engage the bond. To insure the accurate positioning of the strip upon the bond, the operation of the feeding chains 3 and the mechanism for applying the adhesive to, and advancing the strip are so synchronized as to have each bond M enter the folding mechanism and travel therethrough simultaneously with that portion of the strip which is to form the binder therefor, so that the sti ip is folded directly upon the bond, thus greatly simplifying its application thereto. When the separating strip j is used, however, only the bottom of the bond will engage with the strip, this portion of the strip being supported upon the flange 2' and being applied to the bond perfectly flat. The upper folded portion of the strip is prevented from engaging the bond till it has left the folder c thus preventing the strip, under any circumstances, (as through softness in the material of the strip) being applied to the bond except when folded over to the full extent so as to lie perfectly flat without wrinkles. The separator j would also have the effect of defining a straight line along which the strip will be folded. As each bond enters the folder 5 between the flanges c" and 71 thereof, it will pass between the rollers m and their opposed rollers m which not only has the effect of feeding them forwardly at the same speed as the movement of the chains 0, but will keep them perfectly straight and hold them against any tendency to turn by reason of the resistance due to the engagement thereof with the gummed surface of the strip. This engagement continues until the strip has been applied to substantially the entire edge of the bond and will cease only at a point when likelihood of the improper application of the binder to the bond has ceased. As the forward edge of each bond leaves the folder 2' it passes between the presser rollers 7c which apply the laid strip. The roll-- ers 711 mbeing of the same diameter, and running at the same speed, any such displacement of the bond, or any leaf thereof, as would tend to produce an improperly bound bond is avoided. The bonds in passing through the machine, being spaced slightly apart by the clips (1, the section of the strip between the bonds will be folded upon itself and pressed firmly together by the rollers 70 7c. The eccentric connection of the connecting rod Z) with the shaft G will be on center, when the bonds are so positioned that the space between them is between the shears n and n and the various bonds will therefore come to restwhile all of the rollers 70 m are still in engagement with the bond being bound. When all of the mechanisms are thus at rest, the cam {I will force the slide 79 downwardly, turning the shaft 0, and, through the arms 0 and 0, actuating the connecting link 0 and the arm n thus operating the shears to sever the folded strip between any two adjacent bonds. This manner of severing leaves a short tab extending beyond the bond as shown clearly in Fig. 1. This tab is left in order to avoid the necessity for setting the machine so close as to incur a possibility of the mutilation of the bond by said shears. These tabs may be afterward severed by hand. The shears having been actuated will be opened again by the spring 1" and the feeding movement of the strip, chains and rollers will be resumed for the next bond. After each bond has been separated from the others, in this'manner, it is fed by the clips (Z and chains 0 to the end of the machine top, and thence discharged upon the collecting shelf E. In Fig. 1, I have shown a bond upon said shelf.

The operation of the creasing and glue applying mechanism needs no detailed description, such being apparent from the drawings and foregoing description of each.

By an intermittent feeding mechanism for the bonds, and intermittently actuated shears, operated when the feeding movement is at rest, I am enabled to run the machine at a high rate of speed, while the binding strip is being applied to the bond, and yet afford an ample interval of rest for the actuation of the shears without likelihood of mutilating the bonds thereby. This interval of rest also facilitates the feeding of the bonds, as precision is necessary, and cannot be secured when the machine is running continuously at a high rate of speed, with the agencies employed.

It is not my intention to limit the invention to the precise details of construction shown in the drawings, as such may be varied without departing from the spirit and scope of the invention.

Having described my invention, what I claim as new, and desire to have protected by Letters Patent, 'is
